A new downloadable application note from the Fluke website explains how to use a rugged, handheld Fluke 120 Series ScopeMeter within the process industry.
A new downloadable application note from the Fluke website explains how to use a rugged, handheld Fluke 120 Series ScopeMeter within the process industry to test, then troubleshoot, current controlled loops used to control actuators and to monitor temperature, pressure, level and flow.
Fluke 123 and 124 ScopeMeters are truly integrated test tools, combining the three most frequently used service tools: a dual input oscilloscope with 20 or 40MHz bandwidth, a true-RMS multimeter and a paperless recorder in one affordable, easy-to-use instrument.
When testing a current controlled loop, they allow the user to not only provide a digital readout of the instantaneous current but also a graphical display using the oscilloscope function.
This graphical view, with the large bandwidth, enables identification of any interference from low or high frequency signals.
The 600V Category III safety-certified ScopeMeters also offer the opportunity to take measurements over a prolonged time period.
In the TrendPlotT mode, short-term interrupts can be readily spotted on-screen.
On the 124 model, the cursor and real-time clock further aid analysis of recorded phenomena.
The voltage across a suspect component can be checked using the second channel of the ScopeMeter.
The meter also acts as a basic component tester, measuring resistance, capacitance and providing diode test.
Fluke offers a range of process calibration tools, including the 740 Series documenting process calibrators and the 705/707 and 707EX loop calibrators.
The application note "Current controlled loop testing with the Fluke ScopeMeter 120 Series" can be freely downloaded from Fluke's website.
